[GrADS] How to mark the cities in the contour map?

[Qingfang Dai]

Hi,

I revised my gs file as
'reinit'
'open ../Climatology.ctl'
'set grads off'
'set mproj nps'
'set grid off'
'set frame off'
'set cstyle 1'
'set csmooth off'
'set cmin 0.0'
'set clab forced'
'set t 1 1'
'set mpdset ../province'
'd prep'
'set font 1'
'set string 1 tc 3'
'set strsiz 0.15 0.15'
'query w2xy 53.32 -113.58'
'draw mark 3 x y 2'
'printim ../climatology.gif gif white'

But it's still not working.

Thanks.

Qingfang
